Application filed June 22, 1916. Serial No. 105,198.

To all whom it may concern:

Be it known that I, Hnoron ANTOINE BER- GERON, a subject of the King of Great Britain, residing in the city of Montreal, in the Province of Quebec, in the Dominion of anada, have invented certain new and} useful Improvements in Furnaces; and I do hereby declare that the following is a full, clear, and exact description of same.

he invention relates to improvements in v hotwater or steam a furnace, for supplying and the object of the invention is to secure greater efliciency and simplicity ofthe construotion.

are provided, a plurality of cup-shaped sections superposed over one another and connected centrally and a main pipe leading outside of the furnace, the lower ends of said cup shaped sections being connected to -a suitable water supply. Within or below the lower section is provided a fire pot, gas jet or any other suitable means of heating the same, the heated fumes circulating within each section by means of openings provided herein.

The following is a description of the illustrations in which Figure l is a front elevation view of the furnace.

Fig. 2 is a perpendicular cross section of the furnace.

Fig. 3 is a cross section view on lines AA of Fig. 2.

Fig. 4c is a cross section view on lines BB of Fig. 2.

Like numerals of reference indicate correspondin parts in each figure.

In the rawings, 1 is a casing, 2 is the top portion preferably bolted to said casing 1, at 3 by means of the bolt 4 and 5 is a base here shown constructed of cement;

6 is a base plate provided over said base 5 and 7 is a reservoir which may be of any size or shape, but here shown as circular. Petroleum or any other suitable oil, whether crude or refined, may b voir 7 burner secured on said pipe 8.

O is an opening provided through the side of the casing 1, in order to reach the burner 9, and 10 is a door to close said opening.

The casing 1 is provided with a plate 11 which is preferably slanted inwardly in the shape of a funnel, said plate 11 being pro vided with openings 12 and 13 are airopenings or vents provided in said plate at different intervals.

4 is the inner section or smallest section provided with a water circulation therearound and is a header connected on top of said section 14.

6 is a cup shaped section placed over said section 14 and connected, to the header 15 by means'of the nipple 17, said sect-ion 16 being secured above said plate 11 so as to leave a suflicient space for the fumes to circulate around the cup-shaped section 18, which is connected to said section 16 by means of a nipple 19. The said section 18 rests on the plate 11 and is provided at its top portion with openings or passages 20 f0 1 the fumes to reach the cup-shaped section 21, which is connected to said section 18 by the nipple 22 said cup-shaped section 21 being slightly elevated over plate 11 so as to form a passage 23 for the fumes, which coming through the opening 20, will naturally top section 2.

26 is a pipe secured on top of said section 21 leading through said suitable distribution chamber.

he oil in the reservoir 7 is compressed by means of a pump, (not shown in the drawings) and by doing so a more active combustion will be obtained thus forcing the fumes through the top of the section 14 into the compartment provided between the preferably combustion. The gases second combustion will top section 2 to anymeans of mum heat as only the non-combustible gases will escape through the outlets 25.

27 is a main water supply pipe provided with the branches 28 leadin from said main pipe and connected to the ottom or lower part of the sections 14, 16, 18, and 21.

It may be here stated that any other suitable means of combustion can be used in this improved furnace without departing from the spirit of the invention. For instance in place of using oil or gas to produce heat, an ordinary coal fire can be provided inside section 1a to produce heat, and the gases escaping through its combustion can give the same results.

Steam as well as hot water can be produced by this furnace in which the main idea resides in the plurality of cup-shaped sections, overlapping one another so that the gases resulting from combustion will completely inclose the said section before they reach their outlet, and also provide means to ignite these gases at different intervals in order to produce new centers of combustion and thereby obtain the maximum heat from the combustible gases.

Vvhat I claim is 1. A furnace comprising a casing, a plurality of cup shape sections overlapping one another and suitably connected together with said casing, passages provided between said sections for the circulation of the heated fumes, water inlets and water outlets provided in said sections, a base plate secured within said casing and below said sections provided with vent holes or pas- Oopies of this patent may be obtained for sages and means to heat said sections substantially as described.

2. A. furnace comprising a casing, a base plate suitably supported within said casing, a plurality of cup shape sections overlapping one another and suitably connected together, every second section being shorter than the other in order to form a passage between said sections and said base plate,

and passages provided in the uppermost part of the first and third sections, means to supply said sections with water, and means to heat said sections substantially as described.

3. A furnace comprising a casing, provided with fumes outlets, a base plate suitably supported within said casing provided at intervals with a plurality of vent holes, a plurality of cup shape sections overlapping one another and suitably connected together, passages provided the circulation of the heated fumes, water supplying means connected to one end of said sections and means to conduct the hot water or steam from said sections, an oil reservoir provided below said base plate, a burner suitably connected to said reservoir, said burner being suitably disposed centrally of the inner section substantially as described.
